I had a complete mental blank today and couldn’t remember the ‘net use’ windows command to list mapped drives and their sources. I found Managing shared folders from the command line which reminded me!
Found out about this handy utility the other day: ScreenFly.
It allows you to test your website on various device form-factors. Handy!
Today I had to look up the CSS syntax for curved corners and I found this article which suggested:
#example1 {
-moz-border-radius: 15px;
border-radius: 15px;
}
To download a file from the web and send its contents to standard out, try this:
wget -O - -o /dev/null https://www.unconfusable.com
I had a notice from Mailman for one of my lists that there was a message that required administrative attention (i.e. it was spam). The mailman web-interface provides a facility for treating email, however when I went to discard the message it wouldn’t go away. I tried a heap of things and it took a long time to figure out, but eventually I noticed that in the mailman web page the domain name it was using was “intranet.blackbrick.com” whereas that should have been “www.intranet.blackbrick.com”. So I did a little searching about how to configure a list’s base URL and discovered this, which fixed my issue:
/usr/lib/mailman/bin/withlist -l -r fix_url support \ --urlhost=www.intranet.blackbrick.com
Where ‘support’ above is ‘list name’.
Been meaning to get around to reading this white paper from Canonical: What’s new in Ubuntu Server 12.04 LTS.
Here’s an interesting article from way back in 2004: XML on the Web Has Failed.
Learning how to program the EC2 system via the PHP API. I needed to know about RunInstances and AssociateAddress.
You can send Amazon a Request to Remove Email Sending Limitations which by default limit the amount of email traffic instances can process.
Also read about Amazon EC2 Instance IP Addressing and Elastic IP Addresses (EIP).
Although I settled on using the PHP SDK I read the doco for the Java SDK EC2 client: Class AmazonEC2Client. The corresponding PHP API is here. Also How to get list of EC2 instances with Amazon PHP SDK 2 from StackOverflow was useful. All AWS SDKs are here and there are command-line tools. There is AWS SDK for PHP Documentation. This article Provision an Amazon EC2 Instance with PHP was a handy starting place. I also saw the Amazon Elastic Compute Cloud API Reference. I also read AWS SDK for PHP: Run an Amazon EC2 Instance.
I started a project at ProgClub called make-love, which is my server re-instantiation script. It shows how to use the AWS PHP SDK and the r53.php code for programming AWS Route53 DNS services. Documentation on the Route53 client can be found at Ordering Disorder. More on r53.php at SourceForge. I added a new function listAllResourceRecordSets to the Route32 class and commented out some SSL validation code because validation was failing and it’s no big deal to ignore it.
I was getting the error ‘ssl_error_expired_cert_alert’ in Firefox. I checked my client certificate and it hadn’t expired. I checked my CA certificate and it hadn’t expired. It turned out that the problem was that my ca.crl Certificate Revocation List had expired. I fixed that by running jj5-bin empathy-ca-update-crl which says:
echo Updating CRL... openssl ca -gencrl -config ca.cnf -cert cacert.crt -out ca.crl.pem -crldays 365 if [ "$?" -ne "0" ]; then echo Error updating CRL. exit 1 fi echo Exporting CRL to DER format... openssl crl -in ca.crl.pem -outform DER -out ca.crl.der if [ "$?" -ne "0" ]; then echo Error exporting CRL in DER format. exit 1 fi echo Viewing CRL... openssl crl -in ca.crl.pem -noout -text if [ "$?" -ne "0" ]; then echo Error viewing CRL. exit 1 fi
